News

March 25, 2008:

Two new columns have been added to the"Details of All Drifters in the DAC database" (dirall.html) file, to show the ending latitude and ending longitude of each drifter in the database.

January 2008:

The US Navy is presently undergoing a two-ship six month training capacity building exercise in the Gulf of Guinea. AOML, as part of this effort, is providing drifting buoys, training materials and a trainer for this component of the Navy effort. This figure shows tracks of drifters deployed by the HSV 2 Swift. On each track, the star denotes deployment position, the circle shows last transmission position (no circle means, buoy is more than 3 days behind), and the color shows sea surface temperatures in degrees C. (Click on the figure to see a larger map).
During March 11-14, Mr. Shaun Dolk from the Driter Operations Center will be in Ghana to provide drifter, float and XBT training to regional researchers.

August 2007:

On August 19, 2007, an array of 12 hurricane drifters (4 minimets and 8 ADOS) was deployed in the path of category 4 hurricane Dean approaching the Yucatan Peninsula, from a C-130J "Hurricane Hunter" plane. All drifters survived deployment and successfully transmitted their data on the Global Telecomunication System (GTS). Data available at:
http://www.aoml.noaa.gov/phod/trinanes/xbt.html select "hurricane buoys" for "data set".

February 2007:

Drifter 36256 (Drifter # 1250 that completed the first component of the Global Observing System deployed on Sep 18, 2005, was successfully recovered on Feb 21, 2007, at Breast, France, after a 521 days journey through the Atlantic ocean. Both SST and Barometric pressure sensors were reporting good data until its recovery.

Rick Lumpkin is participating in a CLIMODE cruise, aboard the R/V Knorr (US Navy-owned ship operated by WHOI for ocean research community), deploying 30 drifters (from a total of 60 to de deployed) in the North Atlantic. Three of these drifters are part of the Adopt-a-Drifter Program (ADP), established by NOAA/OCO for teachers K-12 from US and foreign countries to provide them with tools to integrate ocean observing system data into their curriculums.

Limnology and Oceanography is hosting a Special Issue on scientific results obtained from autonomous and Lagrangian platforms and sensors (ALPS). All publication costs for this Special Issue will be covered, including Free Access Publication (the entire issue will be freely available online to maximize dissemination). We anticipate publication of 20-25 papers in this Special Issue.

Papers are invited from all disciplines in aquatic sciences. Interdisciplinary studies enabled by ALPS and numerical modeling studies using ALPS are also welcome.

For more details, include abstract and submission deadlines, see: http://aslo.org/lo/alps.html

October 16-20, 2006:

Mayra Pazos and Rick Lumpkin (NOAA/AOML) attended the twenty-second Data Buoy Cooperation Panel (DBCP) DBCP meeting in La Jolla, California. Mayra presented the results of the 2006 drifter performance ("ADB") study, while Rick presented the 2006 Global Drifter Program report and a scientific talk about drifter observations in the path of Category 5 hurricane Rita. A presentation prepared by Jessica Redman on the results of the re-evaluation of the drogue status was also presented by Bill Scuba (SIO) at the meeting.

May 1, 2006:

The Drifter Data Assembly Center recently underwent a reevaluation of all drogue status on drifters deployed since 1998. Due to this, there has been a change in the drogue off date of several drifters. This either lengthened or shortened the life of the drogue depending on the new date chosen. The current database updated through January 2006 has the correct drogue dates. For more information, contact Jessica Redman or Mayra Pazos

October 17-21, 2005:

Craig Engler and Mayra Pazos (NOAA/AOML) attended the twenty-first session of the Data Bouy Cooperation Panel DBCP jointly hosted by the National Meteorological Services and Naval Hydrographical Services in Buenos Aires, Argentina, on 17-21 October, 2005. They gave a presentation on a comparison study of eight clusters of drifters, each from a different manufacturer, deployed at the same time and location in the Atlantic ocean.

September 25, 2005:

Archbishop and Nobel Laureate Desmond Tutu and Captain Jeremy Kingston of the VOS ship MV Explorer deploy a drifter off the coast of South Africa. Archbiship Tutu was participating in the Semester At Sea program aboard the Explorer, which serves as a floating university campus. Every semester more than 600 students sail aboard the Explorer for a learning experience that circumnavigates the globe. Two classes, one from the Congressional School of Virginia and the other from Elsies River High School in South Africa, adopted the drifter and will be tracking its passage through the South Atlantic.

September 18, 2005:

Deployment of drifter number 1250 of the Global Drifter Array, the first fully realized component of the Global Ocean Observing System.
